Specification of Letters Patent.

Patented July .'28, 1914..

Application filed November 17, 1913. Serial No. 801,336.

T0 all w71 om it may concern:

Be it known that I, lVAL'rnn H. GOLES, a citizen of the United States, and a resident of the city of Troy, in the county of Miami and State of Ohio', have invented certain new and useful Improvements'in Nozzles, of which the following is a full, clear, and eX- act description, reference being had to the accompanying drawings, forming part of this specification.

In the use of nozzles for making a very iine jet of liquid, and especiallyv in overhead irrigating systems where alarge number of tiny jets of water must be thrown from a long pipe, it is found that clogging is very likely to occur. It has been found that if a jet of, say, one-thirtysccond of an inch is to be thrown and ifthere is any surface against which the jet must play before it can get out of the nozzle, that then clogging is almost bound to result, no matter howhigh the pressure applied to the liquid. A long passage of needle size will not suffice, therefore, and neither will it do to allow the jet to play against any abutment in the nozzle. Then also the construction of the inlet end of the nozzle often results in clogging by allowing the liquid to enter the nozzle from a' concave surface. This will allow that playing of the currents which will result in the accumulation of tiny particles suliicient to clog up the small inlet.

The object of this invention is to provide a nozzle which will throw a needle et of any practical diameter, say as small as onethirtysecond of an inch, and this without any tendency toy clog.

It is further desired to get a clean stream or jet which is not deflected, and which is therefore especially useful in overhead irrigation work where a great number of jets are used and an even water distribution desired. This I accomplish by that certain construction and arrangement of parts to be hereinafter specifically pointed out and claimed, whereby all eddy currents and deflection and stoppages are eliminated.

In the drawings, Figure l is a .section through a nozzle embodying my invention, mounted in a pipe, with another similar nozzle in elevation. Fig. V9. is an enlarged sectional view of a nozzle of modified form from the rst. Fig. 3 is a plan view, taken with the mouth of the nozzle toward the observer. Fig. l is also a plan view of the sametfrom the inside.

The nozzles' are shown here mounted in a pipe l, by screwthreading their Shanks 2 and screwing the same into properly prepared openings in the pipe. sThe, mouth of the nozzle is formed with the outer walls flattened to make a nut 3 which facilitates insertion and removal of the nozzle. This structure above described forms no essential part of the improved nozzle here, but is merely the means of adapting it to its specially valuable use in an irrigating system. The pipe l is shown here as a two-inch pipe, and this is the size used in an irrigating sys tem. The apertures a, in thenozzles, which communicate directly with the interior of' the pipe are preferably in such a system of one-thirtysecond of an .inch in diameter. The aim is, in irrigatirm, to get the largest amount of waterthrough the smallest hole, wherefore this nozzle is preferably adapted for this purpose.

The aperture or et hole 4 is placed at the cent-er of the convex inner end 5 of the nozzle. The thickness of this end is to be no greater than the diameter of the aperture, if this is possible. The convex form of the surface surrounding the jet hole prevents the lodging of particles of dirt partway across the inlet. lt also prevents the slight eddying of currents which'would take place in a concave form, which would also result in the lodging of particles of dirt. The thinness of the wall, and hence the' extreme shortnessof the passageway through which the jet of liquid must pass, prevents the formation of crusts in the passage, and insures the immediate ejecting from the nozzle of any particle of dirt which Vpasses through the inlet. The nozzle is designed so that the ietof liquid G, when it passes through the jet inlet 5, has no further contactwith the nozzle even upon ordinary deflections. Two forms of barrel are shown, a bell shaped barrel 9, and a cone shaped barrel S. Through each of these the jet will pass without dashing against the walls. T he'mouth l0 of the nozzle is in each case as wide as practical, having regard for strength of parts. This form of barrel and mouthfrernoves possibility of clogging by encrusting or settling of particles of dirt and also projects the jet so as to permit it to maintain its jet form and not break into spray, for a greater distance than it could without protection from wind and particles carried by the wind.

Tt. is now evident from the construction and advantages detailed thatmy improved nozzle is electivo and simple.` Fspecially in the ii'riggixtiingY art it has done away with great disadvantages of the past.

Having thns deserihed my invention, what I claim as new and desire to secure by Letters Patent, is f 1. A nozzle having a minute jet in'let of `stilistantially the same length and diameter,

and a barrel 01"' a Haring shape so that its wall is ont ot rontaet with .the jet at ordinary defieetions.

Q. A nozzle havingr a minute jet inlet of substantially the saine length and diameter, a barrel with Walls laring mitivardlv from the hole and a. mouth at the end oi' the. liarrel of a diameter greater than the mean diameter of the barrel.

A nozzle having a small inlet, a concave inner end in the center of which the inlet is located, a barrel long and Wide in comparison with the inlet and a month at the end of the barrel of `a diameter grlater than the mean diamete of the barrel.

4. A nozzlediaving a minute jet inlet of l 5. In a nozzle, a means for forming aminute jet, means for protecting,- the entrance to said `iet forming means, means for protecting the jet upon leaving said formingr means, said protect-ing means having a long, flaring barrel so as to he out of Contact with the jet in its normal direction.

G. In a nozzle, a means for forming a minute jet, said means being of substantially the same length and cross section, means for protecting' the entrance to said jet forming means, means for protecting the jet nnen leaving said forn'iing means, said protecting' means out ot' contact with the jet in its normal and ordinari7 deflected direction.
